We use the PHEME rumour dataset associated with eight events corresponding to breaking news stories [1]}, which provide tweet-level annotations for stanceWhile the dataset includes data for nine events, here we use the eight events whose tweets are in English, excluding the ninth with tweets in German.. Tweets in this dataset include tree-structured conversations, which are initiated by a tweet about a rumour (source tweet) and nested replies that further discuss the rumour circulated by the source tweet (replying tweets). Details on how the annotation was conducted through crowdsourcing can be found in Zubiaga et al. zubiaga2015crowdsourcing.
